Fixing "Lost" Boot Manager in the BIOS

[evilqueens]

Hello there,

I have a rather odd issue, but I'm sure someone must have done it at some point or another. I recently built a new system and was waiting for my SSD to arrive to use it as my primary partition. In the mean time, I installed Windows 7 on a new Seagate Barracuda 2TB HDD to temporarily gain access to my files on other internal hard disk drives.

Once the new SSD arrived, I installed Windows 7 onto it, started using it as a primary partition, and formatted the Seagate HDD to be used as a secondary storage drive.

Now apparently, my BIOS still thinks that the Seagate HDD has the boot manager and obviously since I formatted the drive, if I try to boot using the boot manager, I'm met with a rather unfriendly error message.

Is there any way to "reset" my BIOS or get it to recognize my SSD and use it as a boot manager? I have an ASUS Maximus V Formula (Z77 Chipset) motherboard for reference.

Usually I'm pretty good with these things, but this is something rather odd that I don't know how to handle.

Any help is much appreciated!

Thank you!

The BCD store needs to be rebuilt because the boot loader is corrupt.

1. Load the Windows 7 installation disc in the disc drive, and then restart the computer.

2. Press a key when you are prompted.

3. Click "Repair your computer".

4. Click the operating system that you want to repair, and then click Next.

5. In the "System Recovery Options" dialog box, click "Command Prompt".

6. Type Bootrec.exe (press enter).

Next, type the following command:

Bootrec.exe /ScanOs (press enter)

The /ScanOs option scans all disks for installations that are compatible with Windows Vista or Windows 7. Additionally, this option displays the entries that are currently not in the BCD store. Use this option when there are Windows Vista or Windows 7 installations that the Boot Manager menu does not list.

If Bootrec.exe /ScanOs doesn't fix the issue, run this command next:

Bootrec.exe /RebuildBcd (press enter)

The /RebuildBcd option scans all disks for installations that are compatible with Windows Vista or Windows 7. Additionally, this option lets you select the installations that you want to add to the BCD store. Use this option when you must completely rebuild the BCD.

Two things to do:
Use fdisk to remove the bootable flag from the MBR of the HDD.
Set up boot order correctly in the BIOS.

If that doesn't help, check that the SSD has the bootable flag set and a working MBR.

If you changed from AHCI to IDE or vice-versa after you installed the OS, you will not be able to boot. Make sure to set the AHCI or IDE before installing the OS.

This happened to me once. Just booted off the Win7 DVD and told it to auto fix errors.

Done.
